Fun Facts About NJ: Famous Firsts
New Jersey has a long record of “firsts.” Some are official milestones, while others are the earliest recorded version of something that grew into a national habit.
| # | First | Where | Year |
|---|---|---|---|
| 1 | First drive-in movie theater | Admiral Wilson Boulevard, Pennsauken | 1933 |
| 2 | First recorded match game of baseball (Knickerbockers vs. the New Yorks) | Elysian Fields, Hoboken | 1846 |
| 3 | First intercollegiate football game (Rutgers vs. Princeton) | College Field, New Brunswick | 1869 |
| 4 | Atlantic City Boardwalk, America’s oldest | Atlantic City | 1870 |
| 5 | First Miss America pageant | Atlantic City | 1921 |
| 6 | First state to ratify the Bill of Rights | New Jersey | 1789 |
| 7 | First underwater vehicle crossing of the Hudson River (Holland Tunnel) | Jersey City to Manhattan | 1927 |
| 8 | First National Reserve (Pinelands National Reserve) | South Jersey | 1978 |
The drive-in charged 25 cents per car plus 25 cents per person, with a $1 maximum per group. Rutgers won that first college football game 6 to 4 on November 6, 1869. The first section of the Atlantic City Boardwalk opened on June 26, 1870, to keep sand out of hotels and rail cars. It was only 8 feet wide and could be taken apart in winter. Today it stretches a little more than 5 miles.
New Jersey Inventions and Innovations
Many fun facts about NJ come from its labs and workshops. Thomas Edison moved into his Menlo Park laboratory in 1876. In 1954, voters renamed Raritan Township as Edison, partly because several New Jersey towns shared the Raritan name.
| # | Invention or breakthrough | Where in NJ | Year |
|---|---|---|---|
| 9 | Phonograph (Thomas Edison) | Menlo Park | 1877 |
| 10 | Light bulb that lasted more than 13 hours (Edison’s team) | Menlo Park | 1879 |
| 11 | Black Maria, called the world’s first film production studio | West Orange | 1893 |
| 12 | Demonstration of the electric telegraph (Samuel Morse and Alfred Vail) | Speedwell Iron Works, Morristown | 1838 |
| 13 | Transistor (Bardeen, Brattain and Shockley) | Bell Labs, Murray Hill | 1947 |
| 14 | Band-Aid adhesive bandage (Earle Dickson) | Highland Park | 1920 |
| 15 | First cultivated blueberry crop | Whitesbog, Burlington County | 1916 |
The 1838 telegraph test sent the message “A patient waiter is no loser” through two miles of wire. Earle Dickson invented the Band-Aid to help his wife, Josephine. In addition, the blueberry breakthrough came from Elizabeth Coleman White, who partnered with botanist Frederick Coville. As a result, the highbush blueberry later became the official state fruit.

NJ Legends vs. Facts
Several popular stories get repeated as fun facts about NJ, but the record is more complicated. Here is how to tell the difference.
